I have a group of objects in my DIT which seems to haven been added at a
time where the server was under heavy write load.

They exist in a slapcat, but are not visible in a search.
They are not fully created but have:
objectClass: top
objectClass: glue
structuralObjectClass: glue
Should this happen?
slapd. 2.4.20. BDB 4.8, using a back_hdb database.
